* when testing, use the sliding resistor and a multimeter
* adjust the resistor from low to high, 0-10k
* watch the current change
* the current test result:
* weak capability: (0.32-10.1)mA

* the data shows:
* weak capability<stronger capability<default capability=default capability2<strongest capability
